A method of reconciling the key discrepancy by exploiting unconditional secure transmission

摘要

In this paper we propose a scheme that unconditional secure transmission is used to implement information reconciliation in key generation. Unconditional secure transmission achieved by associating MIMO beamforming with security code can be safe and reliable. Theoretically, the reconciliation and privacy amplification phase can take advantage of the unconditional communication security to reconciling the key discrepancy, which can simplify the key generation process. This key generation scheme, which implements information reconciliation via the unconditional communication Security achieved by associating MIMO beamforming with security code, is to solve the problem of passive eavesdropping, and we the reliability and security of the method are analyzed and verified.
